From what I read the consensus is dont get that one. Here is a quote from someone that had it that I found somewhere:
"Hi Folks,
Since my last post I have made about 5 more batches. I am less enthusiastic about the Fuelmeister. It takes considerable practice and technique to make it work well. The main issues are 2: 1) it is difficult to get the methanol and lye to mix completely in the mix tank. It can be done, but there needs to be more detail in the instructions to make it clear. A Fuelmeister representative at an energy fair told me it helps to pound the top of the tank to get it to mix. He's right, but this is not indicative of an "industrial grade" quality processor as they advertise it to be. 2) When emptying the mixing tank into the larger tank, it is difficult to get the small tank to empty completely. With 2 gallons left the oil in the big tank tends to start backing up into the smaller tank. That causes a big mess that I had to clean out by hand. Again, with proper technique, that problem has gotten better, but not completely solved. Customer service is excellent. When my mister assembly began leaking, I called Rudi and I had a new improved one within 24 hours. I think I've called 4 times with various problems, and he always takes time to help solve the problem. But overall, I think it's way overpriced. It's not junk, but it's not industrial grade either. When people see it in my garage, they typically say "so where's the $3000 worth of parts?" I feel that they should have perfected the machine before putting it out on the market. After paying $3000 I did not expect to be a beta tester for a machine that is not ready for prime time. The company is responsive, and they intend to make ongoing improvements, but that should have been done way before they started marketing it. If I wanted to fiddle and tinker, I would have made my own Appleseed processor for $200. From what I've learned in the last month, I think they work better too."
I have also heard questions of system safety.
